Re: While Playing the DVD

You probably need to clean out the pc. Get rid of programs that are not needed or used. Do a "Disk Cleanup", Defrag until it takes only about 1-2 min to complete. Get an Anti-spyware/malware as well as an Anti-spyware program and run it once a week. You might want to also invest in more RAM. 512mb these days isnt much.

My dell latitude c510/c610 failing

Sounds like the fan may be failing and need replacement. On a system that age, it is debatable whether it is worth fixing.
You can boot to he resource cd and run fan diags is you want to try and confirm

Fans can be found on EBay

Dell Latitude 1.6 GHz/512/40GB-processor speed seems to be stuck at 221 mhz regardless of what app I am running. Is there a way to adjust the speed of the processor? Or is the processor bad?

The processor is throttled by a process called speed step. This slows the CPU to save power. The same process is used when the processor overheats, and the system throttles to manage the heat production.
So the heatsink and cooling fan should be replaced as the first step in trying to resolve the process.

I want to upgrade my hpdv1000 pentium M processor whats the maximum upgrade allowed for this? i have upgraded it to 2gb ram from 512mb and 250gb hd from 60gb and its doin fine.

You should be able to upgrade the CPU, since it seems that the DV1000's motherboard uses a socket CPU design. But, obviously, HP would rather have you choose the CPU that you want from the beginning and stick with it.
The first thing to do is to check HP website to see what other configurations were/are sold for your model. If they sell it with faster CPUs then you can upgrade to one of them...

In order for a particular processor to be compatible with a particular laptop:
(1) the processor must be physically compatible with the laptop socket, in your case I thing you have a Soket 479 processor
(2) the laptop chipset must support the processor.
(3) the chipset front side bus speed must match the processor front side bus speed, in your case 400Mhz.
(4) the laptop BIOS must support the processor.

So I listed here processors with FSB at 400Mhz, I gues that DV1000 as a 855GM Motherboard that supports only 400Mhz with Socket 479

Disable system bios

never disable system bios, i dont even know if there is a way to do that. the bios exists to provide software for your motherboard to work correctly. i suggest you download from another machine your updated bios version from and put it on a thumbdrive, then boot into safemode and load the file. it should correct any issues you have. there is a possibility that you may have an issue with your new ram. some machines are pretty specific to which types they will take. so get that information from the site when you get your bios update.

good luck!
